Evolution Series Poke-Thru Devices are UL Listed and Classified to U.S. and Canadian safety standards to the

following conditions:

The 6STC Poke-Thru Stem with the 6CFFTC Service Head Fitting, and the 6ATCFF factory assembled Poke-Thru device are

for use with 1-, 1 1/2 -, or 2- hour rated unprotected reinforced concrete floors and 1-, 1 1/2 -, or 2- hour rated floors employing

unprotected steel floor units and concrete topping (D900 Series Designs), or concrete floors with suspended ceilings. (Fire resistive

esigns with suspended ceilings should have provisions for accessibility in the ceiling area below the Poke-Thru fittings).

The assembled Poke-Thru stem and service fitting will not reduce the ratings of the floor assembly when the thickness and type

of concrete (required for the specific rating) are within the specified limits and the fittings are installed as specified:

1. Spacing – Minimum of 2' [610mm] OC and not more than one unit per 65 sq. ft. [6 m

] of floor area in each span.

2. Concrete – Minimum thickness of structural concrete topping of 2 1/4" [57mm] over metal deck or a minimum 3" [76mm]

thick reinforced concrete slab. Unit weight of concrete to be 110 to 155 pcf.

3. Installation – Mounted in a 6" [152mm] diameter hole in concrete per installation instructions accompanying

the fittings. For use with power circuits, data and/or audio/visual cables as tabulated below:

The “TC” suffix letters indicate that the device may be installed on tile or carpet covered concrete floors.
